### Changed
|
||||
- Exponential operations merged with hyperbolic functions
|
||||
- Space is replaced by Group. Space is reserved for vector spaces.
|
||||
- VectorSpace is now a vector space
|
||||
- Buffer factories for primitives moved to MutableBuffer.Companion
|
||||
- NDStructure and NDAlgebra to StructureND and AlgebraND respectively
|
||||
- Real -> Double
|
||||
- Rename `NDStructure` and `NDAlgebra` to `StructureND` and `AlgebraND` respectively
|
||||
- `Real` -> `Double`
|
||||
- DataSets are moved from functions to core
|
||||
- Redesign advanced Chain API
|
||||
- Redesign MST. Remove MSTExpression.
|
||||
- Move MST to core
|
||||
- Redesign `MST`. Remove `MstExpression`.
|
||||
- Move `MST` to core
|
||||
- Separated benchmarks and examples
|
||||
- Rewrite `kmath-ejml` without `ejml-simple` artifact, support sparse matrices
|
||||
- Promote stability of kmath-ast and kmath-kotlingrad to EXPERIMENTAL.
|
||||
- ColumnarData returns nullable column
|
||||
- `MST` is made sealed interface
|
||||
- Replace `MST.Symbolic` by `Symbol`, `Symbol` now implements MST
|
||||
- Remove Any restriction on polynomials
|
||||
- Add `out` variance to type parameters of `StructureND` and its implementations where possible
|
||||
- Rename `DifferentiableMstExpression` to `KotlingradExpression`

- The same classes may be generated and loaded twice, so it is recommended to cache compiled expressions to avoid
